ranked No. 2 in both the AP and Coaches polls, but the BCS computer formula ranked Oregon No. 4, behind No. 2 Nebraska – which had lost to Colorado in its final regular season game – and No. 3 Colorado; this kept Oregon out of the national championship game. The discrepancy caused the BCS committee to alter the ranking system for subsequent years to a formula which, if applied in 2001, would have placed Oregon in the national championship game. The 2001 Ducks instead played at the Fiesta Bowl against Colorado. Oregon's run defense stifled Colorado's running game, holding them to just 49 yards on 31 carries. Harrington passed for 350 yards and led the Ducks to a 38–16 win. Oregon settled for a final 2nd-place ranking in both the AP and Coaches polls. After the 2001 season, offensive coordinator Jeff Tedford left for the head coaching job at California, replaced by Andy Ludwig. The 2003 season was highlighted by a big win against the 5th ranked Michigan Wolverines, ruining Michigan's aspirations of a big season during a trip to a west coast game for the third time in four years. Ludwig resigned as offensive coordinator after a dismal 2004 campaign, the only losing season (5–6) for a Mike Bellotti-coached Oregon team. Recently fired BYU head coach Gary Crowton took the offensive reins; the 2005 season saw a dramatic improvement from 2004, going 10–1 in the regular season, with the only loss to top-ranked USC. In the eighth game of the season against the Arizona Wildcats, the senior starting quarterback for the Ducks, Kellen Clemens, suffered a spiral fracture in his ankle, ending his season and his collegiate career. Despite losing Clemens, the Ducks won the game as well as the rest of their regular season games but lost the Holiday Bowl to the Oklahoma Sooners. In 2006 the team started off well, winning four games to open the season, including a controversial victory against then-ranked No. 11 Oklahoma. But the Oklahoma victory proved to be the high point of the 2006 season; the team eventually fell apart, going 3–5 for the remainder of the regular season, and were pounded by BYU in the Las Vegas Bowl, losing 8–38 in a dismal performance. Gary Crowton left Oregon for the offensive coordinator position at Louisiana State University after the 2006 season; Chip Kelly was hired to replace him in February 2007.
